Technomyrmex albipes can be distinguished from Brachymyrmex species, with which it bears superficial resemblance, by the 12-segmented (versus 9-segmented) antenna, and by the presence of a ventral slit (versus acidopore) on the gaster tip. It can be differentiated from Technomyrmex species by the absence (versus presence) or erect hairs on the mesosoma, and by the gaster which has 4 plates on the dorsal surface and 6 on the ventral surface (versus 5 plates on both surfaces). It is most easily differentiated from Tapinoma sessile by the bicolored with dark head and light body, gaster and appendages (versus uniform brown color). Technomyrmex albipes is distinguished from its fellow introduced congeners by the following combination of characters: (1) no erect hairs on head posterior to eye level; (2) 2 pairs of erect hairs on pronotum, 2 pairs of propodeum, no erect hairs on mesonotum,; (3) hind tarsus distinctly lighter in color than hind femur; and (4) eye length not distinctly greater than length of erect hairs on frontal carinae.
